Abstract: Methods are provided for in-situ detection of varnish and/or deposit precursors in a lubricant in a lubricating environment. An electrostatic accumulator can be used within a lubricating environment to enhance accumulation of varnish and/or deposit precursors on portions of the electrostatic accumulator. The deposits accumulated on the electrostatic accumulator can then be characterized in-situ. The potential difference across portions of the electrostatic accumulator can cause an enhanced rate of deposit accumulation on the electrostatic accumulator, which can facilitate characterization of the tendency of a lubricant to accumulate deposits in the lubricating environment.

Abstract: Systems and methods are provided for enabling communication, without breaching the engine firewall, between a datalogger located on one side of the firewall and one or more sensor devices that are located on the opposite side of the firewall. The systems and methods described herein can allow a transmitting node (i.e., a transmitting datalogger) to transmit collected data (from an auxiliary sensor) to a receiving node (i.e., a receiving datalogger) while reducing or minimizing various difficulties associated with addition of an auxiliary sensor in the engine environment. The transmission of data from the transmitting node to the receiving node can correspond to wired data communication or wireless data communication.
